Abstract

A control apparatus is configured to control an operation of a substrate processing apparatus configured to place at least a monitor substrate therein. The control apparatus controls the operation of the substrate processing apparatus based on a difference between a processing result of the monitor substrate processed by the substrate processing apparatus and a predictive result so as to optimize the monitor substrate loading frequency.
